The alternative is to build your own, buggier, less reliable cron. Smilie

Code:
#!/bin/sh

# Append log files if they already exist
[ -s ~/auto.log ] && exec 1>>~/auto.log
[ -s ~/auto.err ] && exec 2>>~/auto.err

while true
do
        # Reopen logfiles if deleted or truncated
        [ -s ~/auto.log ] || exec 1>~/auto.log
        [ -s ~/auto.err ] || exec 2>~/auto.err

        DATE=$(date +%Y-%m-%d-%H-%M)

        case "${DATE}" in
        ????-??-0[567]-12-0[0-5])
                echo "$DATE:  checking for file"
                if [ -f /path/to/file ]
                then
                        do_something
                else
                        do_something_else
                fi
                ;;
        *)
                ;;
        esac

        sleep 300 # Wait 5 minutes
done

NAME
installsieve - user utility for managing sieve scripts SYNOPSIS
installsieve DESCRIPTION
installsieve is a utility that allows users to manage their sieve scripts kept on the server. OPTIONS
-v <name> View script with the given name. The script if retrieved sucessfully is output to standard output. -l List all of the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active script. -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services. -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten. Upon sucessfully putting the script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since sieve names may not contain a '.'. -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option.. -d <name> Delete the sieve script on the server with <name>. -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen. -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already exists it is overwritten. -u <user> Userid/Authname to use for authentication; by default, the current user. CMU
